CLUTCH.

SPECIFICATION forming part of Letters Patent No. 784,653, dated March 14, 1905. Application filed September 24, 1903. Serial No. 174.412.

To nl?, roll/ont 7115 muy concern:

Be it known that I, O'r'ro S. BEYER, a citizen of the United States of America, and a resident of East Rutherfo rd,county ofBergen, and State of New Jersey, have invented certain new and useful Improvements in Clutches, of which the following is a specification.

The present invention relates generally to clutches, and has more particular reference to means whereby the operating mechanism controlled by the clutch can be caused to operate either intermittently or continuously at will.

In the accompanying drawings I have shown my invention applied in a practical way; but changes of construction may of course be made without departing from the spirit of the invention.

In the said drawings, Figure 1 is a transverse sectional view on the line a: x of Fig. 2. Fig. 2 is a view showing the various members composing the clutch with a section of the power-shaft or driven member, taken on the line g/ y of Fig. 1. Fig. 3 is another section of the power-shaft or driven member, taken on the line s z of Fig. 1.

Similar characters of reference indicate corresponding parts in the different views.

1 indicates a powershaft, in this case the driven member, having a suitable balancewheel 2, in this case the driving member, mounted on the same. The said power-shaft is provided with a longitudinally-extending groove 3 and the said balance-wheel with a corresponding longitudinal groove 4. Located in the said grooves is an oscillatory key 5, having a projection 6, extending at an angle'to the said key. Carried by the driven member is a sleeve T, having the spring-seated pin 8, which normally tends to keep the key 5 in a position where it will engage both' with the grooves in the balance-wheel 2 and in the shaft 1. Mounted on the said sleeve 7 is a tripping member 9. Connected with the usualtreadle is a rod 10, carrying the tripping-lever 11, loosely pivoted on the pin 12 in such a manner -that it can be adjusted so as to be in the path or out of the path of the tripping member 9. The pin 12 is carried by the stop 13, pivoted at on the bracket 19, adapted to be in the path or out of the path of the projection 6, and when in the path of the same to counteract the effect of the spring-seated pin 8 and turn the key 5 out of the groove 4 in the balance-wheel and entirely into the groove of the shaft. The spring-seated member 14 acts as a buffer for the said stop, while the springseated member 15 acts to move the said stop up into the path of the projection 6 when released by the tripping-lever.

16 and 17 are two studs by means of which the tripping-lever 11 can be positioned or adjusted so that the machine will be` made to run either continuously or intermittently.

The spring-seated pin 18 normally tends to keep the lever 11 in position on the pin 12.

l/Vhen it is desired to run the machine intermittently, the lever 11 Will be attached to the bracket 19 by means of the stud 17, so as to be in the path of the tripping member 9. When the latter strikes against the said lever 11, the said lever 11 will be raised up, thereby releasing thestop 13 and allowing the spring-seated pin 15 to move the said stop 13' in the path of the projection 6, which has the effect of moving the key 5 entirely into the groove of the shaft 1, thus stopping the machine. Upon depressing the treadle the lever 11 will move the stop 13 out of the path of the projection 6, thereby allowing the springseated member 8 to move the key 5 into the groove of the balance-wheelQ, starting the machine again.

l/Vhen it is desired to have the machine run y continuously, the lever 11 is shifted over into the position shown by the dotted line in Fig. 2 and attached, by means of the stud 16, to the bracket 19. This will have the effect of keeping the lever 11 out of the path of the tripping member 9.

It is ofcourse not necessary to employ two studs 16 and 17, as one could be used to fasten the lever 11 in both positions.

l/V hat I claim isH 1. In a clutch, the combination of a driving member and a driven member, corresponding grooves in the driving and driven members, an oscillatory key adapted to occupy both grooves or one of said grooves only, means for normally keeping said key in both grooves, a projection on the said key, a pivoted stop for engaging with the said projection to turn the key entirely into one o'i' the said grooves, means for moving said pivoted stop out ot' the path of Vthe projection of the key, a tripping member on the driven member, a tripping-lever pivoted on the stop and adjustable so as to be in contact or out 'of contact with the tripping member aforesaid, and adapted when engaged by the said tripping member to release the stop, and means for moving the said stop into the path of the projection of the key after said stop is released by the tripping member.

2. In a clutch, the combination of a driving member and a driven member, corresponding grooves in the driving' and driven members, an oscillatory key adapted to occupy both grooves or one ol: said grooves only means for normally keeping said key in both grooves, a projection on the said key, a stationary bracket, a stop pivoted on said bracket, means for normally keeping the said stop in the path of the projection of the key, so as to turn the said key entirely into one oi' the said grooves, a tripping member on the driven member, a stud on the pivoted stop, a tripping-lever pivoted on the said stud, andadapted to be adjustably secured on the bracket so as to be in the path or out o't' the path of the tripping' member aforesaid, and means connected to the said tripping-lever for moving the stop out of the path of the projection of the key.
